MAINTENANCE
Snifter Dust Monitor needs very little maintenance. To achieve maximum
reliable operation the recommended maintenance interval is 2 months.
Maintenance is done by removing the unit from the process and cleaning the
sensor rod to prevent signal leakage to ground.
If the particles in the gas are sticky and tend to build up, the cleaning needs to
be done more often.
Check the PC board is firmly connected inside the enclosure. Check LED
indicator cable and signal/power cable connectors are connected correctly.
